Toolbox For Nanoparticle Manipulation Expanded With New Microfluidic Method
2013-06-06 14:03:40

University of Illinois at Urbana-Champaign Researchers at the University of Illinois at Urbana-Champaign have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers. “This method is a first-of-its-kind tool for manipulation and trapping of small nanoparticles in solution,” explained Charles M. Schroeder, an assistant professor in the...

Many solids are produced from melting. Depending on how quickly they cool off, invariably, internal tensile stresses begin to build up. One example are Prince Rupert's Drops, or Dutch tears: you can hit their thick end with a hammer without breaking them while a slight pressure applied to their thin end is enough to shatter the entire tear. The properties of safety or even gorilla glass are determined to a large extent by their internal tensile stresses. However, until now, our understanding...

Big Molecule Models Captured In A Flash

Lawrence Berkeley National Laboratory To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs. Existing methods for solving structure largely depend on crystallized molecules, and the shapes of more than 80,000 proteins in a static state have been solved this way. The majority of the two million proteins in the human body...

A recent study from Stony Brook University examines the presence and effects of gold nanoparticles that are found in everyday items, most notably cosmetics. Dr. Simon Ourian of Epione Beverly Hills says that he expects further studies will find other nanoparticles responsible for accelerating the visual signs of aging. Los Angeles, California (PRWEB) May 23, 2013 According to a April 18, 2013 Stony Brook University report titled “SBU-Led Study Reveals Nanoparticles Found in Everyday...

Grapefruit Nanoparticles Could Provide New Drug-Delivery Method

In recent years, metal nanoparticles have showed great application prospect in the field of biological imaging, cancer diagnosis and treatment due to its unique optical scattering and optical absorption properties. In many metal materials, gold nanoparticles have caused concerns in the field because of its simple preparation, easy to modify advantages. However, the poor stability in physiological fluids environment and the potential toxicity of gold nanoparticles always restricts its...

Stockholm, Apr 26, 2013 - (ACN Newswire) - Nanoparticles are currently used in commercial products ranging from catalysts, polishing media and magnetic fluids to cosmetics and sunscreens. A new review by researchers in Sweden and Spain describes recent work to optimize the synthesis, dispersion and surface functionalization of titania, zinc oxide and ceria - the three main nanoparticles used in photocatalytic, UV-blocking and sunscreen applications.With the commercial success of self-cleaning...

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects. In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first...
